Hi Syd, I have been reading your comments on water in the tanks with interest as I recently removed the shut off valve on the fuselage tank and found some corrosion there. The fuel shut off valve (at the base of the fuselage tank) has a brass insert inside the top (tank side) of the outlet and a pin running through to hold this brass insert in place I presume. I may have broken this pipe off when removing the valve.
Is this brass insert supposed to be a pipe that extend up into the fuel and has a 'ballon' screen covering it, or is that balloon screen mounted on a seperate fitting that protrudes into the fuselage tank? I appreciate your input. Darrel in Victoria. CF-SIT Syd Cohen wrote: > [EMAIL PROTECTED] wrote: > > > My manual seems to indicate that all fuel is useable (in > > flight - I guess).
